Research direction

Start by reproducing the Java example around kernel.invokeAsync(function) and ToolCallBehavior.allowOnlyKernelFunctions(true, functions) with the reported versions. Inspect how the passed functions are handled before the tool call is sent; done means only the supplied kernel functions are invoked and the reported invalid function-name request is no longer produced.

Description

bug triage

Describe the bug
I set the toolcallbehavior of allowOnlyKernelFunctions as true, and passed the functions to the kernel
but the kernel make a functiontoolcall by himself and just invoke it.

To Reproduce
Steps to reproduce the behavior:

         List<KernelFunction<?>> functions = kernel.getPlugins().stream()
                .map(KernelPlugin::getFunctions)
                .map(Map::values)
                .flatMap(Collection::stream)
                .toList();
        FunctionResult<String> preResult = kernel
                .invokeAsync(function)
                .withToolCallBehavior(ToolCallBehavior.allowOnlyKernelFunctions(true, functions))
                .withArguments(
                        KernelFunctionArguments.builder()
                                .withInput(userInput)
                                .withVariable("metadata", metadata)
                                .build())
                .withResultType(ContextVariableTypes.getGlobalVariableTypeForClass(String.class))
                .block();    // occur exception here, for invoke a self-make function

Expected behavior
Only invoke the passed functions.
